Application filed April 30,1906. Serial No: 314,503.

T 0 all whom it nuty concern.-

Be it known that I, ARTHUR H. MARKs, a citizen of the United States,residing at Akron, in the county of Summit and State of Ohio, haveinvented certain new and useful Improvements in Solid Rubber Tires, ofwhich the following is a specification.

This invention relates to improvements in solid rubber tires having aplurality of layers of metal fabric embedded in the base thereof; andthe object is to produce a tire of this type in which the juncturebetween the two parts forming the same occurs within the zone of themetal fabric where it is subjected to less strain, thereby producing astronger tire.

With the above object in view the inventi on consists in the novelfeatures of construction hereinafter fully described, particularlypointed out in the claims, and clearly illustrated by the accompanyingdrawings, in Which Figure 1 is a side elevation of a portion of a tireconstructed in accordance with my invention, and Fig. 2 a transversesectional In forming my tire I first place a single layer 1, ofsuitablemetal fabric, in a straight mold and place upon the top of said fabric asuitable rubber compound. Pressure is then applied and the rubbercompound forced through the interstices of the metal fabric. By thisoperation the tread 2 of the tire is formed and the upper portion 3 ofthe base.

metal fabric are placed and rubber compound and the rubber compoundforced into the interstices of the metal fabric. The lower portion 5 ofthe base of the tire is thus formed. The two parts 3 and 5 are thenplaced in a circular mold and joined, the ends united, and the wholevulcanized.

Heretofore difliculty has been experienced in securing proper adhesionbetween the tread and base portions of the tire, because the line ofadhesion occurred at the least favorable point. In my improved tire thejuncture of the two parts 3 and 5 is at a point below the first layer ofmetal fabric, where it is subjected to lessstrain, and consequently astronger tire is produced.

It will thus be seen that I have provided a tire in which the junctureof the two parts 3 I and 5 is at a point within the zone of the 1 metalfabric-that is, between the upper and lower surfaces of said zone.

I have not claimed in the present application the improved method ofproducing the tire, the same forming the subject-matter of anapplication filed May 11, 1906, Serial N o.

-I'Iaving thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is

1. A rubber tire comprising a tread, and a base having embedded therein,a plurality of layers of reinforcing metal fabric or the like, said tireformed of two parts having the juncture thereof within the zone of themetal fabric.

2. A rubber tire comprising a tread, and a base having embedded thereina plurality of layers of reinforcing metal fabric or the like, said tire'formed of two parts having the juncture thereof between the first layerand the remaining layers of the metal fabric.

3. A rubber tire comprising two parts and having a reinforcing metalfabric or the like embedded therein, the line of demarcation between thetwo parts being within the zone of the metal fabric.

4. A rubber tire of the type having a plurality of layers of metalfabric or the like embedded in the base characterized by being formed oftwo parts having the joint between the same within the zone of the metalfabric.

5. A rubber tire of the type having a plurality of layers of metalfabric or the like embedded in the base, formed of two parts having thejoint between the same at a point below the first layer of metal fabric.

6. A rubber tire of the type having a plurality of layers of metalfabric or the like embedded in the base, characterized by having thetread and upper portion of the base formed as one part with one or morelayers of the metal fabric embedded in said upper portion of the base,and the lower portion of the base forming the other part and having oneor more layers of the metal fabric embedded therein, the two parts beingfirmly united to form an integral whole.

In testimony whereof I affix my signature in presence of two witnesses.

ARTHUR H. MARKS.
